Abstract

Phenol formaldehyde resin can be modified by adding phenol derivates, such as tertiary butylphenol (TBP), hydroquinone (HQ), and p-amino phenol (AP). This research aimed at studying the effect of phenol derivates and pH on the resin characteristic and porous carbon. Polymerization was carried out in a three-neck flask, equipped with a magnetic stirrer, heating jacket and thermometer in a base condition, at 90°C and 1 to 3 hours reaction time. The resin was then cooled and neutralized. The curing process was carried out where resin was added by pTSA and then stirred to reach homogeneous condition. The resin was then heated at 150°C for ± 10 minutes. The carbonization process was conducted by pyrolizing the phenolic resin at 800°C for 1 hour. The result showed that the optimum condition of phenol formaldehyde reaction was at pH 8. Resin product that had optimum physical properties was PFTBP resin. It had a density of 1.18 g/cm3 and hardness value of 17.2 g/mm2. Among the phenolic resin materials produced, the PF carbon showed the highest product quality, indicated by high BET surface area of 836.7 m2/g and high iodine number of 862.3 mg/g.
